Uncorrected radii (top) and corrected radii (bottom) as a function of M_* (left) and M_B (right) both at ɀ = 0. Note that, “R” denotes for this work the optical radius (R_opt), while for K20, “R” denotes the circularised 28 mag/arcsec² isophotal radius in the Β band. The figure utilises the same colour and symbol coding as in Fig. 2, and the statistical definitions are as described in Section 2.2.
